Structures such as armor, microelectronics, or critical infrastructure systems lack effective, real-time sensing systems to detect damage events of interest, such as an impact from a ballistic object, a tamper event, a physical impact such as from debris (such as airborne or space debris), or other damage which may affect the structural integrity or cause failure.
The Navy has developed an electronic monitoring system to produce real-time information on a variety of impact events, including structural, perimeter, and armor integrity failure conditions.
One instance of the invention provides sensors to areas where impacts may occur from a ballistic means or other damage producing collisions. When used in the detection of a ballistic strike, the technology can further estimate the ballistic object’s origin, relative velocity, and size
The critical components of the system are a multitude of acoustic monitors placed throughout an object such as car, aircraft or even body armor. These are connected to a signal processor and measurement device. A monitor and user interface provides a visual display of the damage data.
Applications for this technology are diverse and include:
- Sensing of space vehicle damage during liftoff
- Detection of bullet point of injury to a person wearing body armor
- Identification of fatigue cracks in an aircraft fuselage
- Determination of the extent of damage in an auto collision in order to deploy airbags to occupied seats
- Damage detection to critical electrical components which would trigger taking those electronics off-line, reassigning hardware, and continue functioning so that mitigation actions can be taken in real-time
- Identification of breached containers holding sensitive documents, information, or materials
